Powdery Mildew on Basil
I heard today on NPR that powdery mildew was appearing on basil plants and was glad to figure out what was wrong with my basil. The leaves appear yellow and if you look at the underside, you see very fine gray or almost black powder.
I am just wondering if anyone else in the Denver area has this problem, and, if so, what you are doing (if anything) about it. I Googled it and apparently it isn't toxic to humans and you should just destroy the affected leaves.
I'd love to know if someone else has it.
